Cu0- doped TiO2 nanofibers as potential photocatalyst and antimicrobial agent

• Formation of metallic copper nanoparticles-doped titania nanofibers.
• Nanofibers appeared a high photodegradation activity for different azo dyes.
• Nanofibers revealed a good antimicrobial activity toward waterborne microorganism.
• Nanofibers depict a high photodegradation activity for three cycles.

Cu0 nanoparticles (NPs)-doped TiO2 nanofibers (NFs) were prepared as an effective photodegradation of three azo dyes as well as an antimicrobial agent under visible light. Fabrication of one dimensional zero-valent Cu nanoparticles-doped TiO2 nanofibers with high aspect ratio have been successfully synthesized by simple and low cost; electrospinning technique followed by hydrothermal process. The photocatalytic activity of introduced nanofibers was evaluated by performing of three azo dyes. Catalytic NFs show a superior photodegaradation activity under visible light as well as good antimicrobial activity. Moreover, photocatalyst nanofibers appeared good stability, which was used for three cycles without regeneration.
